I eral tainers iii any convenient manner. As shown it delivers water to one of such Water con: tainers c and water is thence-conducted to the other Water containers in succession by a. so that the body of water in each container is separate from and independent of the body of Water in each of the other containers, .so far as the generation of steam therefrom is con- Suitable connections, such' as shown, for example, at c3 in Fig. (i, may `be provided for so connecting different containers of the battery as to permit any one to be cut out of operation and to be removed for vAny one or all of the containers may be connected to the gage glass at, as iiidicated at c* in Fig. 2.

In each of the Water containers c is located an electrical heating element, the sevheating elements being preferably connected, as indicated diagrammatically in F ig. 7. AAs shown in Figs. l, 9. and 3, each heating element may consist of a base plate d with a vertical post or illai` (Z, of suitable non-conducting material, provided with suitable clips d2 to receive the current resist antelements c, of graphite or other suitable imaterial, in which' tlie'energy of the -electricall current is converted into heat, and

with suitable electrical. connections c which are extended through the base al and through the plate b. The support or holder (t, d ior the elements c is preferably formed or rovided also with venes or wings d" w ich stand out between the elements c, as clearly shown in Fig. 2. The elements e are connected at top and 'bottom alternately in series from the binding posts e. 5

Another form of heating element is shown 40 in Fig. in which the post or pillar Il,

erected on the base plate d, is chambered longitudinally, as at d4, and the resistant element c* is coiled, in an open coil. around the outside of the post or pillar tl', one end being connected to the corresponding binding post externally to the post or pillar d While the other end is connected to the other binding post through the lower end of the post or pillar.

0 In case it should be desired to remove one of the heating elements for repair or any other pui-pose, there is provided a substitute bottom'plate, shown at 7 in Fig. 5, which inav be .bolted or secured in place of the plate b and the base of the heating element.

In the embodiment of the invention represented iii Figs. 8 and 9, the shell or casing' /12 is rectangular in Ishape and the independent water containers are formed therein by 'G0 partitions a?, which may be successively lower from the inlet cnd of the shell tothe outer end, so as to permit the ovciilow watci to pass from one to the other in succession The easing may be provided as before with a st lety valve a', a steam gage 012, pet cocks a,

a gage glass at, a Water inlet a@ and a steam outlet 'In each Water container c* is an independent heating element, constructed substantially as previously described but changed in form so that it may be adapted to thec1 rectangular Water container. As shown, it comprises a. supporting block or plate d* provided with suitable clamps (Z2 to support the heating rods e, which are connected in series with the binding posts c. which pass through the bottom of the shell u?. The block (ZX is provided 'with walls ff to prevent the jumping of electric current from one rod to anotl In the use of the improved generator all of the energy of a heating clement is applied in the heating of a body of lwater, the vol unie of which is such as to secure' the greatest economy and the greatest ctiicicncy in the use of the electric current, while the capacity of the Whole generator may bc regulated according to requirements by using a suitable number of the independent water containers and their heating elements. Moreover,isiiice all of the water containers and their heating elements are combined in one structure, with a common steam space, the Waste of heat through radiation into the atmosphere, when only a portion of the water containers and heating elements are in use, is reduced to a minimum, the heat. which not used iii one of the water containers in developing steam therein being taken up by the water in an adjacent container which is not then in use. Furthermore, repairs can be made readily at any time without requiring more tha a brief discontinuance ofwtlic use of the whole generator, since the heating tions made between the remaining water containers and heating elements to permit the use ofsuch remaining water containers and heating 4elements tobe continued.

It will be understood that the: forni and arrangement of the outer shell or casing and of the water containers and their heating elements and connections may be varied to invention is not, therefore, restricted to the precise construction and arrangement shown and described herein.

I claim as m" invention:

1. An electrical steam generator, compris ing a common shell or casing, a plurality of independent water containers therein, each adapted to receive and hold a body of water separate from and independent of that in cach of the other containers, and communicatiiig with a common steam space, and a plurality of independent electrical heating, elements distributed in the several Water y containers, whereby the Water in each con: tainer may be heated independently of that l in the other containers.

element can be removed easily from any one of the water containers and suitable connecl suit dierent conditions of use, and that the ndepenlent Water containers therein, each adapt-oel to receive and holdl a body of water separate from and'independent of that in Jr @sich of the other containers, and communi- Eating "with common steam space, a pluraltv of independent heating elements distribn he several Water containers, each of salici ylief 11g elements consisting of a base 5t@ willi :i vertical, pillar and radially i- .ruling insulating Wings, heating 'rods on said Support, and connected in fm elofftrioal steam g '(11o1\tor7 comprising r.. common Shell or c sing, a plurality of inflependoot Water AContainers inserted through tho bottom of said casing and @noli container being adapted to receive and hold a. body of witter Separate from amd imlependent of that. in @ach of the other oou miners, plates secured to the bottom of Ytho Shell or casing to Support andv retain' the waiter ontziioors., and :1 plurality of indo- Qomlent felectriozil heating elements (glistrioi ntf-cl in thosovornl 'water contninor.
